Technical Field

The invention relates to the technical field of ore mining and crushing, in particular to efficient mining equipment and method integrating ore mining and crushing.

Background

The ore refers to a stone containing a certain valuable mineral substance extracted from a mine, and the stone can be applied to engineering fields such as metal mines, metallurgical industry, chemical industry, building industry, iron (highway) road construction units, cement industry, sandstone industry and the like after being processed step by step through crushing, smashing and the like. The ores are divided into buried layer ores and bare layer ores, wherein the buried layer ores are buried in the mountain body, the bare layer ores are exposed on the ground surface, and the bare layer ores are exposed outside, so that mining is convenient. The work step of the naked layer ore of present exploitation does, the vibrating breaker who adopts mining equipment earlier is with the surface breakage of naked layer ore, so that the stone in the naked ore bed is dredged, then the workman uses the scraper bowl of excavator to shovel into the packing box of transport vechicle with the stone of loosing in, it is regional to transport appointed windrow through the transport vechicle with the stone, then the workman shovels into the jaw crusher with the stone, in passing through the jaw crusher, when the stone enters into the broken station of breaker, two crushing rollers extrusion broken stone in the breaker, thereby finally obtain required small-grain-diameter ore from the discharge gate department of breaker.

However, although the current mining and crushing methods can process small particle size ores, the following drawbacks still exist: 1. the stone in the naked ore deposit condenses into the pie, and only one breaker among the mining equipment, leads to the workman to need repetitious operation breaker so that the impact drilling rod on it strikes many times on the pie stone, just can obtain the bulk stone after the impact, just can make things convenient for subsequent jaw breaker to carry out the breakage smoothly, and this is the extraction efficiency who has reduced the ore undoubtedly. 2. The loose stone blocks need to be transported to the designated crushing area by a transport vehicle, the intermediate transport distance is long, the crushing time is undoubtedly delayed, and the ore mining efficiency is also reduced. 3. The workman will shovel into the stone behind the jaw crusher in with the stone, and the stone is piled up in a large number between two crushing rollers, and the flow speed of stone is slow, leads to waiting for a long time just can break away accumulational stone, and this is undoubtedly the crushing efficiency who has reduced the stone. 4. The hardness of stone is great, and is big to two crushing roller losses in the jaw crusher to reduced the life of crushing roller, and the surface majority of some stones is the arc form, lead to the stone hardly to eat into the crushing district between two crushing rollers in, further reduction the crushing efficiency of stone. 5. The jaw crusher can only crush the stone once, which causes that the crushed small-particle-size ore still carries with the large-particle-size ore, so that the defect of uneven crushing exists. Therefore, an apparatus for improving ore mining efficiency, stone crushing efficiency and uniformity of particle size of crushed ore is needed.
